Application filed .Tune 22, 1909. Serial No. 503,619.

To all whom it may concern:

Be it known that I, GEORGE W. Connow, a citizen of the United States,and resident of New York, in the county of New York and State of NewYork, have invented "certain new and useful Improvements in Safet-Razors, of which the following is a speci cation.

This invention relates to improvements in safety razors.

In the drawings: Fi re 1 is a top View of the blade holder an guard.Fig. 2 is a side view of the blade holder, uard and handle. Fig. 3 is afront edge View of the blade clamp, detached. Fig. 4 is a side edge viewof the blade holder, detached. Fig. 5 is a side view of thehandle,-detached. Fig.

6 is a top view of the blade holder, detached.

ness. The ears 12 12 forming thepivoted connection between the holderand handle, are partly severed from, and turned down on the same piecewhich forms the body of the holder. Struck up from the same piece toprotrude above the body of the holder are the dogs -13 13, the heads 14-14 whereof, are rounded in the forms of thin pads adapted to extendinto round perforations formed in the razor blades. The shanks of thesedogs are ex tended backward away from the guard edge 15- of the holder.The disposition of the shanks forms resisting members to receive andhold the blade on the holder, while the clamp 11 is being adjusted. Setout from the sides of the holder are the lugs -16 -16- against which theclamping arms '17 -l7-- of the clamp impinge and are arrested. The bladeholder -10- is hingedly mounted on the handle -18 at 19- by the rivetheaded in -20.- To limit the backward throw 0 the holder -10 the handlehas formed thereon the extension -21- against which the holder strikesand rests. The upper surface of the holder 10- is curved transversely toits longest dimension, it being the desire to hold the blade in a rigidbended shape on said holder. As stated, the blade is pcrforated toreceivethe pads l4 l4-.

To maintain the blade --Z- on the holder, and to bend it on the same, Ihave provided the clamp -11--. The clamp is curved to conformsubstantially to the holder 10- and is hingedly mounted at 22 upon thehandle -18 the hinge being formed by a rivet headed pin 24.-. The arms17 are formed as shown, and are provided with the flat bent lugs23 -23whereby the arms and clamp are forced into position. The hinge mountings-20 and -'22- are separated to produce a longer radius for the movementof the clamp .11- than that produced by the shorter ears -12- -12 bywhich the movement of the holder --10- is regulated. The distance of thehinge at 22 from the body of the clamp -11-- is less than the distancefrom the said hinge -22- to the upper surface of the holder 10- whenmeasured through the hinge at -19---. This causes the clamp to be drawnupon to bear against the upper surface of the holder l0 to hold anyinterposed blade thereon. It is by this eccentric movement of the holderand clamp that they are drawn together as the arms 17-- 17- and theears-12- -12 approach alinement.

In the operation of inserting or removing a blade from the holder, thefollowing acts are performed: The clamp '17- and the holder-10 areforced forward. to the positions shown in dotted lines at Fi 5 ofdrawings. The blade Z is now a justed on the holder --10- in such mannerthat the pads -14 14;- are held in the perforationsformed in the blade.The clamp 11- is then swung back until it strikes upon the blade on theholder -10-. From this point the clamp and holder move in unison,assuming the final position as shown in Fig. 1 and Fig. 2 of drawings.Tn this final position the lines of the ears 12 12- and the arms -l7 l7'fromthe hinge mountings l9 and --22 coincide, clamping the blade firmlyin position and being locked against disadjustment.

The blade which it is desired to use is the usual two-edgedblade. Whenemploying such, the blade is reversed in the holder during use. When itis desired to use the straight single edged blade, the form of holderemployed is that shown at Fig. 9 of drawings wherein the dogs 13 -13 aredispensed with. The back -25- is upturned at the rear edge, of theholder I Against this'back 25 the blade is' adjusted and held when theclamp 11 is swung into position.

Having thus described this invention, what is claimed is; v

1. A safety razor comprising a handle having a blade holder hingedlymounted thereon, at one end thereof, said holder being curved in thedirection of the line of cut; a thin flexible razor blade and a clampconvexly curved transversely to its longest dimension, hinged to thesaid handle at a point thereon below the hinge of the blade holderthereon so that the clamp is adapted to move over the blade holdereccentrically to the movement of the blade'holder.

, 2. A safety razor comprising a handle having a blade holder-hingedlymounted thereon atone end thereof, said holder be ing curved in' thedirection of the line of .cut and having hinge wings formed inteone end'thereof, havin a blade holder with sto 5 formed integral y therefrom atthe en s and back thereof, and a clamp member each hingedly mounted onsaid handle the one above theother at one end thereof by hinge arms ofdifferent lengths so that the clamp is adapted to move over the razorblade member positioned on the blade holder, eccentrically to themovement of the blade holder as they swing to the clamping positionagainst stops. 7

4. A safet razor. comprising a handle having a bla e holder member and aclamp member each hingedly mounted thereon, at one end thereof, by hingearms of difi'erent lengths, the pivots of sald arms separated a distancegreater than the difference in the length of said hinge arms to draw thesaid members together as they swing to the clamp-ing position, therebyholding clamped a thin flexlble razor blade firmly in position for use.
